CAUTION
Do not drop or hit this Spindle, as shock can damage to the internal components.
①
Do not connect this Spindle to the reduction gear. This may cause collet breakage by overload.
②
Be sure to clean the collet, the inside of the spindle before replacing the tool. If ground
③
particles or metal chips stick to the inside of the spindle or the collet, damage to the collet or
spindle can occur due to the loss of precision.
When cleaning a Spindle, stop the brushless motor and remove debris with a soft brush or a
④
cloth. Do not blow air into the End of Spindle Area (refer to section " 6 - 2 Outside View " ) with
compressed air as foreign particles or cutting debris may get into the ball bearing.
Always clean the tool shank before installing the tool in the Spindle.
⑤
When sizing the correct collet size to the tool shank diameter, a tolerance of +0 〜 - 0.01mm is
⑥
strongly recommended. A tool shank within the +0 〜 - 0.1mm range is mountable, however,
using a tool other than recommended may cause poor concentricity and or insufficient tool
shank gripping force.
Select suitable products or tools for all applications. Do not exceed the capabilities of the
⑦
Spindle or tools.
Do not stop the supplied cooling air to the brushless motor during operation of the machine.
⑧
Removing the air pressure from the brushless motor causes a loss of purging, allowing the
Spindle to ingest coolant and debris. This will cause damage to the Spindle.
Carefully direct coolant spray directly on the tool. Do not spray directly on the Spindle body.
⑨
If large amount spray directly on the Spindle, it may cause excess load of the Spindle rotation
with loss of durability to the Spindle.
Stop working immediately when abnormal rotation or unusual vibration are observed.
⑩
Immediately, please check the content of section " 14. TROUBLESHOOTING".
Always check if the tool and collet are damaged before and after operating.
⑪
If the collet show signs of wear or damage, replace it before a malfunction or additional
⑫
damage occurs.
After installation, repair, initial operation, or long periods of non operation, please refer to
⑬
section " 12. BREAK-IN PROCEDURE " detailed in Table. 2. When checking the spindle, no
vibration or unusual sound should be observed during rotation.
Do not disassemble, modify or attempt to repair this Spindle. Additional damage will occur
⑭
to the internal components. Service must be performed by NSK NAKANISHI or an authorized
service center.
When using this Spindle for mass production, please consider the purchase of an additional
⑮
Spindle to be used as a back-up in case of emergency.
